All this shows is man cannot manipulate God's will (Big surprise). I have seen prayers answered and unanswered. I would not dare to claim that 8400 prayers could sway God, but would claim that 1 prayer can make all the difference that is needed. Sometimes physical recovery is not in the person's best interest and it is obviously not always the will of God. I find that in my weakest moments when I feel all is lost or the pain seems to be unbearable, I do not pray for an end to the pain, suffering, or ailment, but for comfort through it. I have found that this comfort comes from Christ and while he does not take it all away, it is bearable and I feel my prayers answered. Perhaps my cross is not too large for me to handle when I choose to be near Him.
Kalahnikid,
I am not sure if you posted this in sarcasm or if you are seriously troubled by it. Frankly I wouldn't pay it any attention, but if you would like to further discuss this, I welcome you in public or private.
